FIELD

The present disclosure relates, in exemplary embodiments, to a lighted wall-mounted display. In exemplary embodiments, the present disclosure relates to wall-mounted lighting panels and face plates for displaying information and alerting observers to changing conditions.

BACKGROUND

Wall-mounted display units, such as monitors and sensors often need to be viewed to determine the status of the systems being monitored or sensed. In many uses the display unit is mounted to a wall in a hallway, such as in a hospital, laboratory, or the like. Typically, a user views the unit by standing or sitting generally in front of the unit so that he or she is looking straight at the display because the illuminated display usually has a limited off-axis viewing angle. For certain types of monitoring, a color change is an adequate signal indicating a change in status. It would be desirable for someone who needs to monitor the display unit to be able to observe a status change (such as a color or light pattern change) or other visual or audible signal) from down a hall where the angle of viewing the display is not straight on at the display unit. It would be desirable to have a display unit that could project a light signal in a wider off-axis viewing angle, such as if a user is positioned in a hallway and views the display unit down the hall from the user's location; i.e., a viewing angle approaching 90 degrees from the aforesaid straight on viewing angle. It would also be desirable for a display unit to be able to illuminate so that the viewing angle can be seen from both off-axis directions, i.e., a total of about 180 degrees, or possibly even more.

SUMMARY

In exemplary embodiments, an apparatus is described for providing side-viewable illumination of a wall-mounted plate, the apparatus comprising a face plate having a face, sides and an opening; a back plate having a front face, rear face and sides, the sides having at least a portion thereof being transparent or translucent; a controller (such as a printed circuit board); and, at least one light-emitting device associated with the back plate rear face and positioned such that light emitted by the light-emitting device at least partially passes through the back plate sides.

In exemplary embodiments, the bezel further includes a display device opening adapted to receive a portion of the display device, the display device opening having an edge that is at least partially coated with a reflective coating such that at least a portion of light from the at least one light-emitting device directed toward the display device opening edge is reflected away from the display device opening edge and back toward the bezel edge.

In other exemplary embodiments, an apparatus is described for providing side-viewable illumination of a wall-mounted plate, the apparatus comprising a face plate having a front face, a rear face, sides, and a display opening; a rear plate adapted to mount either to or within a wall or other structure. Such apparatus further includes a bezel having a front surface, a rear surface, exterior side edges, interior side edges, a rim extending at least partially around the bezel exterior side edges and defining a recess area, and at least one opening extending at least partially through the bezel. The apparatus may further comprise at least one light-emitting device adapted to be received within the bezel opening whereby light emanating from the at least one light-emitting device is at least partially directed toward the bezel side edge such that the light is visible when viewed at an angle generally parallel to or at an acute angle with respect to the plane of front surface of the faceplate. The apparatus may further comprise a controller in electrical communication with the at least one light-emitting device for controlling the at least one light-emitting device.
